Target.com has two promos that stack on beauty and personal care items
Spend $30 get a $10 giftcard on select beauty & personal care items (exclusions apply)
$5 giftcard with 4 beauty & personal care (exclusions apply)
Both gift cards, total $15, will be added to cart. Best is to spend $30 with 4 items.
Example I found is head&shoulders shampoo, pantene pro-v classic clean shampoo
NOTE: Most items will have the $10 GC promo only (good deal in itself), but you have to look for the ones that have both to get both GCs.
